这是转义JSON。格式很好，如下所示：

[
  {
    "title": "Brand Primary",
    "value": "#2185D0",
    "_id": "627a0637cf178d93e50be224cc07cd6e"
  },
  {
    "title": "Brand Secondary",
    "value": "transparent",
    "_id": "017280d9ec94a585c2de0bee8f49d8fb"
  },
  {
    "title": "Typo normal",
    "value": "#383838",
    "_id": "ff77119a11466c8d7a0efd612109fe6a"
  },
  {
    "title": "Typo on Brand Base",
    "value": "#383838",
    "_id": "8a3c1eebb8067b37fc47fc505f44b8b4"
  },
  {
    "value": "rgb(255, 255, 255)",
    "title": "Typo on Brand Active",
    "_id": "66fe7ced-3ef8-4dac-92c7-568d604c2931"
  }
]

要更新其中的值，您需要：

获取值类似这样：

$color_items = get_option( \'cornerstone_color_items\' );
$color_items = stripslashes( $color_items );
$color_items = json_decode( $color_items );

foreach ( $color_items as $color_item ) {
    if ( \'Brand Primary\' === $color_item->title ) {
        $color_item->value = \'NEW VALUE HERE\';
        break;
    }
}

$color_items = wp_json_encode( $color_items );
$color_items = addslashes( $color_items );

update_option( \'cornerstone_color_items\', $color_items );
